Title: Process of dyeing cellulose acetate textile materials of high acetyl value, and dyebaths for use therein
IPC: D06P1/673
Filed: 1957-09-23
Abstract: Textile materials comprising fibres of cellulose acetate of acetyl value at least 60% are coloured by applying thereto a dyebath in which the dyestuff is dissolved in a mixture of water, a monohydric aliphatic alcohol, an alkali metal or ammonium thiocyanate, and, if desired, acetic acid, the concentration of thiocyanate being such that the dyebath causes coalescence of fibres of acetone-soluble cellulose acetate of acetyl value 54-55% so that textile material made therefrom loses its fibrous character, but does not damage fibres of cellulose acetate of acetyl value at least 60%.  Preferably the cellulose acetate has an acetyl value of at least 61% and the fabric thereof has a maximum safe ironing temperature below about 200 DEG C.  Dye concentration is preferably up to about 5%, especially from about 0,01% to about 4%, based on the weight of the dyebath.  A preferred dyebath comprises a dyestuff dissolved in from 5-25 parts of acetic acid, 5-55 parts of water, 25-70 parts of the alcohol and 5-12 parts of an alkali metal or ammonium thiocyanate, all parts being by weight.  The dyebath may be at 10-50 DEG C., and the textile material carrying adhering dyebath may be rinsed with water and then dried.  Preferably, textile material in fabric form is passed continuously into the dyebath and is then continuously rinsed and dried, e.g, fabric may be padded with the dyebath and, after a contact time of 2-30 seconds, may be rinsed in water at below 30 DEG C.  An alternative dyebath comprises a dyestuff dissolved in from 5-35 parts of water, 65-95 parts of the alcohol and 8-14 parts of alkali-metal or ammonium thiocyanate. This dyebath may be at 10-50 DEG C., and the textile material carrying adhering dyebath is preferably dried at below 65 DEG C. before rinsing with water. Preferably, textile material in fabric form is passed continuously into this dyebath and is then continuously dried and rinsed, e.g. fabric may be padded with the dyebath and, after a contact time of 2-30 seconds, may be dried at below 65 DEG C. and then rinsed in water at below 30 DEG C.  After dyeing the textile material may be heat-treated to increase its crystallinity and crystalline order index.  In the above dyebaths, the preferred alcohol is ethyl alcohol, but methyl, isopropyl, n-butyl and isobutyl alcohols may also be used, and the preferred thiocyanate is sodium thiocyanate. Suitable dyestuffs include acid, premetallized, direct cotton and leuco vat ester dyestuffs, and cellulose acetate disperse dyestuffs of the slow-dyeing high-temperature type, which are soluble in the dyebaths used. Numerous dyestuffs are specified.  Specifications 791,391 and 824,398 are referred to.

Abstract: 974,935. Refrigerating. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. Aug. 21, 1961 [Sept. 2, 1960], No. 30067/61. Heading F4H. In a refrigerating machine comprising an elongated shell enclosing evaporator and condenser spaces which are longitudinally coextensive with the shell and an exterior compressor whose inlet and outlet are connected to the evaporator and condenser section respectively, the evaporator is arranged wholly above the condenser section and the sections are separated by a baffle. As shown in Figs. 1 and 2, the baffle comprises plates 16, 18 defining space 70 which is filled with refrigerant vapour through duct 68 so as to prevent heat transfer between evaporator space 20 and condenser space 22. In operation, refrigerant vapour from space 20 passes via eliminators 80 to inlet duet 41 of the centrifugal compressor, Fig. 3. The impeller 40 drives the refrigerant via scroll-like easing 36 and duct 47, passing outside the shell 12, Fig. 2, over heat transfer tubes 26 in the condenser space 22. The condensed refrigerant flows into collector 54 and is passed under control of float valve 56 via tubes 60, 62 and 63 to nozzles 66 which spray liquid refrigerant downwardly over evaporator heat transfer tubes 24, these tubes being positioned in a rectangular array to ensure uniform wetting. Alternatively, the liquid refrigerant may be sprayed upwardly on to tubes 24 or the tubes may be wetted by flooding. In Fig. 7, the refrigerant from tube 60 is fed to the bottom of evaporator space 20 and excess refrigerant is collected in chamber 110 containing a pump 114 which feeds the overhead spray pipes 62, 63. Alternative arrangements of the compressor ducts are described. For example, the compressed refrigerant may be fed from two opposite points on scroll-like casing 86, Fig. 6, via ducts 88, 90, which pass through the evaporator section of the shell into the top of the condenser section.

Abstract: 1402713 Circumferential-flow compressors LINTOTT ENG Ltd 29 Sept 1972 [30 June 1971] 30579/71 Heading F1C In a vortex compressor comprising a bladed impeller rotatable in a generally toroidal chamber, the impeller has a fixed, integral or separately made flow-inducing ring on or adjacent to but extending clear of the blades to assist formation of the vortex. In the compressor shown in Fig. 1, a disc 4 attached to the impeller 1 has holes 5 for the passage of fluid between adjacent blades 2. The periphery 6 of the disc forms the flow-inducing ring for promoting vortical flow within the toroidal chamber 7. Fig. 8 shows a compressor in which a flow-inducing ring 42 is formed on the impeller 35 adjacent each set of blades 36-41. The three sets of blades on each side of the impeller are operated in series to compress fluid from an inlet 50 or 51 to an outlet 52 common to both sides. Ducts (not shown) within the casing 43 interconnect the successive stages. In addition to promoting vortical flow, each ring 42 acts as a seal ring to reduce leakage. A single-stage impeller may comprise sheet aluminium blades (22'), Fig. 6, (not shown), set into radial slots in the impeller periphery and bent forwardly in the direction of rotation. A flow-inducing ring (30) encircling the blade tips is attached by epoxy resin. The impeller shown in Fig. 5 has arcuate slots 23 milled into one side 24, whereby the material remaining between adjacent slots forms blades 22. A flow-inducing ring 6 is attached to the side 24. A groove (33'), Fig. 7 (not shown), may be provided in a wall of the casing to extend part way from the outlet region towards the inlet region, the resultant bleed of fluid from the outlet region to the inlet region helping to establish vortical flow at the inlet.

[Class 38 (iv).] Substituting souces in service; starting ; prime movers.-Generating units of different capacities are connected to a load circuit individually according to the demand. Each unit is provided with a separate starter s as shown in Figs. 1 and 2 and a common automatic controller C shown in Figs. 1 and 3. Referring to Fig. 2 a load on the mains 1<1> 1<2> closes a circuit from battery B through winding 7b to close switch 7 and remove a short circuit 9 from the magneto of the internal-combustion engine E coupled to the generator A. Winding 5a is energized to close a switch 5 and the generator motors to start the engine E. A governor switch 8 opens upon the engine reaching full speed to de-energize winding 5a. When the generator volts rise winding 6b closes switch 6 to connect the generator to the circuit 1<1>, 1<2>. Removal of load in circuit 1<1>, 1<2> de-energizes retaining winding 6c and opens switch 7 to short-circuit the magneto and de-energize winding 6b and shut down the unit. Referring to Fig. 3 the smaller unit No. 1 is normally connected to the load circuit L<1>, L<2>. An increase in load above a predetermined amount energizes windings 11c, 11d to close contacts 11b and place winding 11e across unit No. 2. A current flows through winding 11e from the battery in the starter connected with unit No. 2 described above and unit No. 2 is started. When the voltage of unit No. 2 rises winding 10c is energized to disconnect unit No. 1 and connect unit No. 2 to the load circuit L<1>, L<2>. The smaller unit then shuts down. Contacts 11b are kept closed by winding 11d. Should the load drop relay 11 drops out to close contacts 11a and energize winding 13a and close contact 13 and connect resistance r<2> and winding 12a across the mains of unit No. 1 to effect starting of this unit.
